论文摘要
电力系统状态估计在能源管理系统（EMS）中起着基本和关键作用。为了实现高性能和准确的系统状态估计，本文提出了基于图计算的分布式状态估计方法。首先，电力系统网络分为多个领域。选择参考总线，每个区域都在这些总线上安装PMU。然后，将系统网络转换为多个独立领域。这样，可以在每个区域并行进行电力系统状态估计，并且在没有准确性的情况下获得了估计的系统状态。 IEEE 118-BUS系统和MP 10790-BUS系统用于验证结果的准确性并呈现有希望的计算性能。
Power system state estimation plays a fundamental and critical role in the energy management system (EMS). To achieve a high performance and accurate system states estimation, a graph computing based distributed state estimation approach is proposed in this paper. Firstly, a power system network is divided into multiple areas. Reference buses are selected with PMUs being installed at these buses for each area. Then, the system network is converted into multiple independent areas. In this way, the power system state estimation could be conducted in parallel for each area and the estimated system states are obtained without compromise of accuracy. IEEE 118-bus system and MP 10790-bus system are employed to verify the results accuracy and present the promising computation performance.
